Performance analysis: USE method by Brendan Gregg

[Alan Coopersmith]

I put together this list for someone who asked yesterday "When you have a
performance problem, where do you start troubleshooting/analyzing?" and
figured as long as I made it, might as well share it more widely in case
someone here hasn't seen it yet.

This is the method put together by Brendan Gregg, explained in blogs,
slides & video:

While those are the Solaris/OpenSolaris links, you can also find versions for
some other OS'es linked to from them, or from his home page at

And because Brendan never rests, he's now written an ACM Queue article
on the subject, and presented a talk on it at this year's Usenix LISA
conference:
